A novel T-Type Multilevel Inverter for Electric Vehicle and Grid-connected applications

摘要

The invention of multilevel converters has set forth many advantages in power electronics field. The design of those converters with reduced losses and high efficient topologies attracts many researchers who work in the field of power electronics. In this work, a novel configuration of T-Type multilevel inverter for grid-connected systems is proposed. It is the combination of an H-bridge configuration along with an asymmetrical circuit made up of bidirectional switches. Both the configurations operate at different switching frequencies which lead to a hybrid switching technique. The T-Type MLI is designed in such a way to produce an output of 3 level& 5 levels, and the comparison on THD levels is made. The overall performance of the newly designed inverter is analyzed with the help of simulation. The simulation of the newly designed topology is done using MATLAB and the results are obtained.
